Veteran Donates Kidney to Friend He Served With Almost Two Decades Ago: 'It's Just That Military Brotherhood'

An army veteran took the meaning of military brotherhood to heart when he gave his kidney to a friend that he served with more than two decades ago.

Kai Johns, 44, was diagnosed with polycystic kidney disease in November after he experience flu-like symptoms.

“I went to urgent care and said I needed to get to the hospital as soon as possible. They immediately admitted me and told me I had six percent kidney function,” Johns told InsideEdition.com. “My body was just filled with toxins.”
